qdoc doesn't throw a warning for \generatelist if passed an invalid parameter

https://doc.qt.io/QtAndroidAutomotive-6.4/qtaa-examples.html#hvac-control

is created by passing a group name to \generatelist. the expected behavior was to be the same as using \annotatedlist but with no annotation. there was no warning thrown.

What was generated looked like this was occurring, but actually, they are not links to the documentation entities they are just targets on the HTML page.

So the first line of the \generatelist command documentation could become "The \generatelist command expands to a list of links to documentation entities depending on the parameter passed."

and the code was updated to catch this misuse and throw a warning.

Alternatively, this implied feature could be implemented.
